bashfully

The adverb 'bashfully' is built upon the adjective 'bashful', which emerged in the mid-16th century. Its core, 'bash', is a shortening of the now-obsolete verb 'abash', meaning to destroy one's composure or cause embarrassment. 'Abash' itself entered Middle English from Anglo-French, tracing back to Latin 'ex-' (thoroughly) and 'batare' (to gape, be astonished). The suffix '-ful' attaches to form the adjective describing a person prone to such a state. Finally, the Old English adverbial suffix '-ly' is appended, creating a word that literally describes acting in a manner full of abashment, evolving into its modern sense of shy or self-conscious behavior.
